Google’s emissions up 51% as AI electricity demand derails efforts to go green

A picture


Google’s carbon emissions have soared by 51% since 2019 as artificial intelligence hampers the tech company’s efforts to go green.While the corporation has invested in renewable energy and carbon removal technology, it has failed to curb its scope 3 emissions, which are those further down the supply chain, and are in large part influenced by a growth in datacentre capacity required to power artificial intelligence.The company reported a 27% increase in year-on-year electricity consumption as it struggles to decarbonise as quickly as its energy needs increase.Datacentres play a crucial role in training and operating the models that underpin AI models such as Google’s Gemini and OpenAI’s GPT-4, which powers the ChatGPT chatbot.The International Energy Agency estimates that datacentres’ total electricity consumption could double from 2022 levels to 1,000TWh (terawatt hours) in 2026, approximately Japan’s level of electricity demand.

AI will result in datacentres using 4,5% of global energy generation by 2030, according to calculations by the research firm SemiAnalysis,The report also raises concerns that the rapid evolution of AI may drive “non-linear growth in energy demand”, making future energy needs and emissions trajectories more difficult to predict,Another issue Google highlighted is lack of progress on new forms of low-carbon electricity generation,Small Modular Reactors (SMRs), miniature nuclear plants that are supposed to be quick and easy to build and get on the grid, have been hailed as a way to decarbonise datacentres.

There were hopes that areas with many datacentres could have one or more SMR and that would reduce the huge carbon footprint from the electricity used by these datacentres, which are more in demand due to AI use.The report said these were behind schedule: “A key challenge is the slower-than-needed deployment of carbon-free energy technologies at scale, and getting there by 2030 will be very difficult.While we continue to invest in promising technologies like advanced geothermal and SMRs, their widespread adoption hasn’t yet been achieved because they’re early-stage, relatively costly, and poorly incentivised by current regulatory structures.”It added that scope 3 remained a “challenge”, as Google’s total ambition-based emissions were 11.5m tons of CO₂-equivalent gases, representing an 11% year-over-year increase and a 51% increase compared with the 2019 base year.

This was “primarily driven by increases in supply chain emissions” and scope 3 emissions increased by 22% in 2024.Sign up to Down to EarthThe planet's most important stories.Get all the week's environment news - the good, the bad and the essentialafter newsletter promotionGoogle is racing to buy clean energy to power its systems, and since 2010, the company has signed more than 170 agreements to purchase over 22 gigawatts of clean energy.In 2024, 25 of these came online to add 2.5GW of new clean energy to its operations.

It was also a record year for clean energy deals, with the company signing contracts for 8GW.The company has met one of its environmental targets early: eliminating plastic packaging.Google announced today that packaging for new Google products launched and manufactured in 2024 was 100% plastic-free.Its goal was to achieve this by the end of 2025.In the report, the company also said AI could have a “net positive potential” on climate, because it hoped the emissions reductions enabled by AI applications would be greater than the emissions generated by the AI itself, including its energy consumption from datacentres.

Google is aiming to help individuals, cities and other partners collectively reduce 1GT (gigaton) of their carbon-equivalent emissions annually by 2030 using AI products,These can, for example, help predict energy use and therefore reduce wastage, and map the solar potential of buildings so panels are put in the right place and generate the maximum electricity,

Carlos Alcaraz escapes first-round scare as Fabio Fognini tests his limits

Carlos Alcaraz said he was proud to have squeezed into the second round after struggling with his nerves and the heat on Centre Court during his dramatic five-set win against Fabio Fognini on Monday.In searing temperatures, Alcaraz started his pursuit of a third consecutive Wimbledon title by outlasting the veteran Italian 7-5, 6-7 (1), 7-5, 2-6, 6-1 after 4hr 37min on-court.“I’m getting mature and I know how to deal with some situations,” the Spaniard said. “I always say that the champions always find a way. I really want to see myself in that [list] of champions

Emma Raducanu too strong for teenager Mimi Xu in British battle

“Come on Britain!” echoed through the sweltering 32C heat on No 1 Court as Emma Raducanu defeated Mimi Xu in straight sets, 6-3, 6-3. The all-British clash featured two players – attired similarly in matching outfits and golf visors – who captivated the home crowd.While Raducanu has been a fan favourite since her fairytale 2021 US Open triumph, the grand slam ­debutant Xu, ranked No 300 in the world, has impressed in junior circuits and shown significant promise on the senior tour.“It was an interesting dynamic today,” Raducanu said. “It is really awkward playing a Brit, especially someone younger

Farewell tradition, hello robots: Wimbledon adjusts to life without line judges

Sometimes progress registers simply as absence, and so it was on the opening day of Wimbledon this year when the pursuit of greater accuracy led to the disappearance of the tournament’s famous line judges.Electronic line calls are now in operation in SW19, bringing the championships into line with the grand slam tournaments in Melbourne and New York and also the ATP Tour. The French Open still uses line judges. But the shift to camera‑based, AI‑enhanced decision-making cuts deeper at Wimbledon, where up to 300 line judges have been a colourful part of the tournament’s ensemble cast for the past 147 years.With protests outside the gates (albeit with tongue in cheek) and ambivalence among fans, there were also unexpected reactions from players to the changes

Sibley hits 305 as Surrey break run record: county cricket day two – as it happened

On and on went big bad Dom. Past 200, past his highest previous score, past 250 and, with a sprinted single that left him spreadeagled in the Oval dust, to 300.Sibley clambered to his feet, raised his bat and soaked up the warm applause for a mammoth effort of concentration: 28 fours, two sixes and 472 balls of toil as the mercury rose. He joins an elite club of triple-centurions for Surrey at the Oval, in Mark Ramprakash, Kevin Pietersen, Bobby Abel, Jack Hobbs and Tom Hayward. At the other end, Dan Lawrence shimmied 174 and Will Jacks 119 as Surrey set their record first-class score, finally putting Durham out of their misery at 820 for nine

Wimbledon diary: strawberry sandwiches, pricey rackets and Oliver Tarvet’s expenses

“Where are the strawberries and cream?” was among the more unexpected questions for one of Wimbledon’s army of volunteer stewards as the crowd streamed through the gates on Monday morning, given that the answer is “absolutely everywhere you look”. It was a different story, though, at the local branch of Marks & Spencer, where 300 packs of the chain’s specially commissioned strawberry & crème sandwich, a staple food for influencers on Instagram and TikTok in recent days, ran out shortly after 9am. A sample did make it into the media room, however, and while strawberries “paired with whipped cream cheese on sweetened bread” might sound like the losing team’s product idea on week two of The Apprentice, it has to be said … it’s very edible.There was an air of genteel bedlam in the main Wimbledon shop as the first wave of merch-hungry tennis fans poured through the doors in search of SW19-branded booty. The demand for hats and towels was, not surprisingly, rather stronger than that for sweatshirts and hoodies, and no one at all seemed inclined to lug around one of the giant tennis rackets – designed to be hung on the wall, apparently – that are the most expensive single items in the shop at £600 a pop

Mystery swirls around Bumrah as unchanged England overlook Archer for second Test

One of the many delights of leafy south Birmingham is when an international cricket team is in town and residents stumble across them training on the Colts Ground at Edgbaston. Folks could be heading for a stroll in Cannon Hill Park, or their weekly shop at Aldi, only to suddenly find themselves watching Jasprit Bumrah let fly.Sadly, the fences were covered with tarpaulins after some hecklers over the weekend. There was a decent subplot playing out inside as India trained, too, over whether Bumrah will play the sold-out second Test that starts . Having bowled these past few days, the man himself offered a passing “hopefully”
